Cov Ntawv Thov
1. Tshuaj Nruab Nrab
Siv los ua lub tsev thaiv hauv cov hluavtaws ntawm cov tshuaj sib xyaw.
Lub Halogen Txav (Br thiab f) Muab cov chaw rau xaiv ua haujlwm ntawm cov kev sib txuas lus (piv txwv li, heck, lossis buchwald-hartwal sib txuas).
Ua rau cov kev tsim kho ntawm Heterocyclic tshuaj nrog kev txhim kho cov chaw muag tshuaj cov chaw muag tshuaj.
2. Agochnical synthesis
Ua haujlwm ua ib nrab hauv nruab nrab hauv kev tsim cov tshuaj tua kab, tshuaj tua kab, thiab fungicides.
Lub halogenated pyridine scaffold yog tshwm sim hauv agochemicals vim nws cov kev ua haujlwm roj ntsha.
3. Cov Khoom Taw Qhia
Siv nyob rau hauv kev tsim cov ntaub ntawv ua haujlwm xws li cov organic semiconductors, kev ua fluorescent probes, lossis ligands rau hlau cov nyom.
Cov tshuaj fluorine atom tuaj yeem txhim kho thermal stability thiab liplophilicity, muaj nqis rau cov khoom ua tau zoo.
4. Txuj Ci Kev Tshawb Fawb
Ib qho tseem ceeb substrate hauv cov tshuaj chemical thiab heterocyclic sib xyaw synthesis.
Muab ib lub platform rau kev kawm cov qauv-kev ua haujlwm sib raug zoo (SAR) thiab Halogen cuam tshuam rau kev ua haujlwm biological.
Cov txiaj ntsig
✅ Xaiv Reactivity
Lub bromine atom yog ib pawg tawm rau pawg rau kev sib txuas lus hla kev sib txuas, tso cai kho tshuaj kho mob.
Fluorine imparts hluav taws xob cuam tshuam thiab txhim kho metabolic ruaj khov nyob rau hauv cov molecules molecules.
✅ Txhim Kho Kev Ua Haujlwm Roj ntsha
Halogenated Pyridines feem ntau qhia tau txhim kho kev txhim kho hauv kev sib haum xeeb, thiab enzyme tsis kam.
Ua tau muaj peev xwm
Lub hauv paus fluorine txhim kho tshuaj lom neeg thiab kev siv hluav taws xob, uas muaj txiaj ntsig hauv ob qho tib si tshuaj thiab agnemicals.
✅ Khoom siv hluavtility
Ua rau cov synthesis ntawm ntau cov derivatives rau cov ntawv thov sib txawv.
Tag
3-bromo-5-fluoropyridine (CASE 407-20-5) yog qhov muaj txiaj ntsig zoo siv nyob rau hauv cov tshuaj, agnocemical, thiab cov khoom siv science tshawb nrhiav. Nws sib xyaw ntawm bromine thiab fluorine hloov chaw muaj cov khoom siv hluavtaws hauv lub hom phiaj ua ke, ua rau nws lub tsev tseem ceeb rau kev txhim kho cov ntawv loj.
